Benefits of technology
This patent is about a system that uses a camera and a manipulator to guide and recognize work pieces without using a calibration target. The system can acquire a two-dimensional image of a reference work piece and the distance between the reference work piece and the manipulator. The system can then learn the reference work piece based on the image and the distance to guide the manipulator to the work piece. The technical effect of this system is that it provides a more efficient and accurate way to guide and recognize work pieces, improving production efficiency and accuracy.
Problems solved by technology
These systems typically involve complicated mathematical formulas and lengthy calibration procedures.
These existing systems currently can take a long time to perform for each type of work piece and can often required skilled people to calibrate them.
Furthermore, changing the type of work piece in-line may not be feasible due to the calibration requirements between work pieces, decreasing flexibility and productivity of the manufacturing or production facility.

Embodiment Construction
[0012]FIG. 1 is a schematic view of an embodiment of a visual guidance and recognition system 10 that does not require calibration, as disclosed herein. The visual guidance and recognition system 10 comprises a servo actuated manipulator 20, a camera 30, a manipulator controller 40 and a recognition controller 50. The manipulator 20 has an end-effector 60 that physically varies depending on the function to which the manipulator has been programmed to perform. Non-limiting examples of end-effectors 60 include arms, welders, graspers, paint guns, and other tools required or desired for the manipulator 20 to perform its function. The end-effector 60 typically extends from a face plate 65 of the manipulator 20. The camera 30 is typically mounted on or in fixed relation to the face plate 65 of the manipulator 20. The vision recognition system 10 operates to recognize a work piece 70 and position the manipulator 20 accurately in relation to the work piece 70. The work piece 70 can be any ...

Disclosed herein are embodiments and methods of a visual guidance and recognition system requiring no calibration. One embodiment of the system comprises a servo actuated manipulator configured to perform a function, a camera mounted on the face plate of the manipulator, and a recognition controller configured to acquire a two dimensional image of the work piece. The manipulator controller is configured to receive and store the face plate position at a distance “A” between the reference work piece and the manipulator along an axis of the reference work piece when the reference work piece is in the camera's region of interest. The recognition controller is configured to learn the work piece from the image and the distance “A”. During operation, a work piece is recognized with the system, and the manipulator is accurately positioned with respect to the work piece so that the manipulator can accurately perform its function.
Description
FIELD OF THE INVENTION[0001]The present invention relates to an automated guidance and recognition system for recognizing a work piece in three-dimensional space and being able to align a servo actuated manipulator relative to the work piece.BACKGROUND[0002]Due to the demand on manufacturers for higher quality parts and increased production, automation has increasingly been incorporated into manufacturing and assembly processes. Robots are one such automation technique that has been used extensively across many manufacturing industries. Robots can perform a wide range of functions such as inspection, welding, moving and manipulating parts, painting, etc. To perform a particular function, a robot must be programmed to perform the function on a particular work piece. However, this programming is based on a set of ideal parameters. The actual parameters between an industrial robot and a particular work piece differ from the ideal ones due to, for example, slight changes in the robots p...
